How Much Is 4 Tablespoons of Cornstarch in Ounces?
4 tablespoons of cornstarch weighs 1.13 oz. This is based on cornstarch having a density of 128g per cup. Because tablespoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 4 tablespoons.
Formula and Step-by-Step
- Start with 4 tablespoons of cornstarch
- 1 tablespoon of cornstarch = 8g
- 4 × 8 = 32g
- Convert grams to ounces: 32 ÷ 28.3495 = 1.13 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For the most consistent results, weigh cornstarch on a kitchen scale. Volume measurements can vary by 20-30% depending on how the flour is scooped.

Understanding the Units
What is a Tablespoon?
A tablespoon (tbsp) is a US customary unit of volume equal to 14.787 milliliters, 3 teaspoons, or 1/16 of a cup. It is commonly used for measuring smaller amounts of ingredients.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
